rhel7中，targetcli使用两位数的分区后缀名字（比如sda10）而导致的问题

根据redhat.com文章&＃xff1a;targetcli causes calltrace with the particular partition names which include 2 digits&＃xff0c;链接见下&＃xff1a;


https://access.redhat.com/solutions/2180861

建议&＃xff1a;

Currently, there is no package to fix this issue. Red Hat is handling this issue in RHBZ#1312270
The workaround is to avoid creation iqn with the partition whose name contains two digits.好吧&＃xff0c;遇到bug了。。。不用sda10了&＃xff0c;于是执行如下的命令&＃xff1a;
